The thermometer is removed carefully without touching its tip, and held at the eye
level to clearly see the mercury column and the numbers. The point where the mercury
column reaches indicates the body temperature. It is read immediately after taking the

temperature.

The normal temperature of a human body ranges between 97.7–99.5°F or 36.5–37.5°C.

Doctors use thermometer to check body temperature of their patients. We also check
our body temperature when we are not well.

QUICK LOOK

1. Length of an object is measured using a ruler, metre rod or measuring tape.

2. Capacity is the measure of amount of liquid which a container can hold.

3. Capacity is measured using a graduated beaker, measuring cylinder or a measuring glass.
4. Mass of an object is the amount of matter in a body.
5. A weighing machine or a beam balance is used to measure the mass of an object.

6. Temperature is the degree of hotness or coldness of a body.
